HD74ALVC16244 16-bit Buffer / Driver with 3-state Outputs ADE-205-206 (Z) Preliminary 1st. Edition January 1998 Description This 16-bit buffer / driver is designed for 2.3 V to 3.6 V V CC operation. The HD74ALVC16244 is designed specifically to improve the performance and density of 3-state memory address drivers, clock drivers, and bus oriented receivers and transmitters. The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. It provides true outputs and symmetrical active-low output-enable (OE) inputs. To ensure the high impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current sinking capability of the driver. Features • VCC = 2.3 V to 3.
